sure:

link\_to(“my\_text”, { :action =\> “your\_action”, :some\_param =\> “my\_text”  
})

this would give you “my\_text” as params[:some\_param] in your action. You  
can add any number of parameters that way with whatever content you  
want.

Yes it is possible.

link\_to\_function(name, \*args, &block)

Returns a link that will trigger a JavaScript function using the  
onclick handler and return false after the fact.

The function argument can be omitted in favor of an update\_page block,  
which evaluates to a string when the template is rendered (instead of  
making an Ajax request first).

)

Thanks
